本研究是將螢光發光團連結二茂鐵單元利用azine作為架橋基,形成2,3-diaza-1,3-butadiene鍵結的化合物11、16、17,預計形成具有螢光性質的螢光離子感測器,並且我們改變發光團上的取代基與取代基數目的不同。在電化學的研究中,二茂鐵的衍生物都顯示一個可逆的氧化還原波,且取代基數目的多寡會影響鐵原子的半波電位(7,0.36V,11,0.44V),(16,0.405V,17,0.549V),我們推測二茂鐵單元與發光團之間有進行電子傳遞的情形,並且發現取代基具有拉電子基的性質。在晶體結構的部分,Cp上的Fe→C鍵平均鍵長(11 = 2.046 Å,16 = 2.042 Å),C=N鍵長大約為1.27 Å,N-N單鍵鍵長大約1.42 Å。在光學研究在UV-Vis吸收光譜中我們觀察到triarylamine在254、395 nm,Anthracene在254、395 nm都有典型的π→π*的吸收,並且發現取代基的數目越多,發光團的吸收峰就越明顯。此外我們在螢光激發光譜中也觀察到,取代基的數量越多,發光團的螢光強度也越強。
Our strategy for this system is fluorophore unit probe connecting to a ferrocene unit through a 2,3-diaza-1,3-butadiene bridge such as 11、16、17. The cyclic voltammogram of 11、16、17 shows one successive reversible electron redox wave corresponding to the oxidation of the ferrocene moiety. In addition, the E1/2 wave is (7,0.36V,11,0.44V), (16,0.405V,17,0.549V), there exists some electronic communication between the two active centers through the azine bridige. We found substituent is electron-withdrawing groups. In the crystal structure , Fe → C average bond length (11 = 2.046 Å, 16 = 2.042 Å) , C = N bond length of about 1.27 Å, N-N bond length about 1.42 Å. In the optical, UV -Vis absorption spectroscopy, we observed that triarylamine at 254, 395 nm, anthracene at 254, 395 nm are typical of π → π * absorption, and we also observed that the greater the number of substituent, the more intensity of the absorption and the stronger the fluorescence intensity.
